MITRE ATT&CK
T1059.005 Visual Basic T1204.002 Malicious File

The file is a Microsoft Word document containing VBA macros, specifically a Document_Open macro. ClamAV detected the file as Doc.Trojan.Thus-8. The presence of a Document_Open macro strongly suggests malicious intent, likely to download and execute a second-stage payload. The embedded URL, while confirmed benign, is listed as an IOC. No document body content was available to analyze for further context.

Heuristics 5

  • ClamAV: Doc.Trojan.Thus-8 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Doc.Trojan.Thus-8
  • ClamAV detection on extracted artifact critical EXTRACTED_FILE_CLAMAV
    ClamAV flagged at least one file extracted from inside this sample. Even when the wrapping document carries no AV detection of its own, a hit on the carved artifact is a strong indicator the sample is a delivery vehicle.
  • Document_Open macro high OLE_VBA_DOCOPEN
    Document_Open macro
  • VBA macros detected medium OLE_VBA_MACROS
    Document contains VBA macro code
  • Embedded URL info EMBEDDED_URL
    One or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.
    URL http://www.apple.com/DTDs/PropertyList-1.0.dtd
